Specification of Letters Patent. Application filed September 30, 1911.

Patented May 28,1912. Serial No. 652,182.

To all whom it may concern:

Be it known that I, WILLIAM G. NAUGH- TON, a citizen of the UnitedStates, residing at Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented new and useful Improvements inFenders, of which the following is a specification.

The invention has for its general object the provision of a deviceintended for use with trolley cars, and adapted to operate automaticallyupon impact with an object on the track, to apply the brakes and throwthe reversing mechanism of the car.

Other objects will appear and be better understood from the followingdescription taken in connection with the accompanying drawings, inwhich,

Figure 1 is a side elevation partly in section of the forward portion ofa car provided with my improved device. Fig.2 is a detail horizontalsection of the connection between the buffer frame and shaft whichoperates the reversing mechanism and taken approximately on the line 22of Fig. 1.

The fluid pressure brake system (0 herein shown as applied to the car 5is of wellknown construction and includes the line made up of the pipes5 and 6 which connect with the controlling valve 7 located adjacent tothe dash 8. The car 6 is of the wellknown electric type and is shownmerely to illustrate one application of my invention.

. A second or supplemental controlling valve 9 is arranged below thefloor 10 of the car and is connected to the pipes 5 and 6 by means ofpipes 11 and 12. The stem 13 of the valve 9 has an operating stem in theform of a bell crank lever, the arms 14. and 15 of which arerespectively connected with the fender 16 and buffer frame 17 by meansof links 18 and 19. The fender 16 is supported from the floor 10 of thecar and is adapted to swing. The opposite sides of this fender overliethe rails and carry permanent magnets 20 which are normally spaced fromthe rails. The buffer frame, by virtue of its link and lever connectionwith the fender serves, in addition to a purpose to be described later,to hold the fender 16 so that the magnets thereof will be slightlyspaced from the rails.

The controller box 21 arranged adjacent to the dash 8 has the usualcontrolling lever 22 and also a reversing lever 23. This mechanism, withthe exception of the reversing lever 23, is of well-known constructionand forms no part of the present invention; therefore, a detaildescription of the same need not be given. The shaft 24 connected to thereversing lever 23 extends through the floor 10 of the car and isprovided at its lower end with a crank arm 25. A link 26 connects thecrank arm 25 with a bracket 27 carried by the buffer frame 17 and isadapted to turn the shaft 24 and also the reversing lever 23 when thebuffer frame swings inwardly, this turning of the-reversing lever havingthe effect of reversing the current and likewise the power mechanism,whereby the car is caused to move rearwardly.

A plunger 28 extends through the floor 10 of the car and moves upwardlywhen the buffer frame swings inwardly so that by depressing this plungerthe buffer frame is moved outwardly and the parts connected theretorestored to their normal positions.

In Fig. 1 the parts are shown in their normal positions and it will bemanifest that when an object strikes the buffer frame, the latter willswing inwardly, and as it does so the reversing mechanism will beoperated in .the manner previously described and the controlling valve 9operated through the link 19 so as to permit the air to actuate thebrakes in the ordinary manner. It will be seen that during this movementof the parts the arm let of the bell crank will move downwardly, therebylowering or swinging rearwardly the horizontal portion 29 of the fender16 until the magnets 20 thereof con tact with the rails. This contactbetween the magnets and track will serve to prevent the accidentallifting or swinging forwardly of the fender 16, thus preventing theobject struck by the buffer frame from being passed over by the fenderand by the wheels before the car shall have been brought to astandstill.

Although I have shown and described one embodiment of my invention itisto be understood that I am not to be limited to the specific structurenor to the particular ar rangement of the parts herein described andclaimed since it will be seen that various changes may be made, in thescope of the appended claim without departing from the spirit orsacrificing any of the advantages of the invention.

What I claim as new is In combination with a car, a fluid pressure brakesystem therefor including a controlling valve and reversing mechanismincluding a reversing lever; of a fender pivoted to the car a movablebuffer frame pivotally connected to the car and. arranged in front ofthe fender, means connecting the controlling valve with the fender andbuffer frame and serving to support the fender in spaced relation to thetrack and to operate the controlling valve upon movement of the fenderor buffer frame, and a connection between the reversing lever and bufierframe, for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
